∗1 The offset voltage EOB is a potential difference between VRB and a point of position where the voltage

drops equivalent to 1/2 LSB of the voltage when the output data changes from "00000000" to "00000001".

EOT is a potential difference between VRT and a potential of point where the voltage rises equivalent to

1/2 LSB of the voltage when the output data changes from "11111111" to "11111110".
